Uma das principais manifestações patológicas conhecidas apresentadas em estruturas metálicas é a corrosão, manifestação responsável por deteriorar o aço e consequentemente comprometer sua estabilidade e segurança. Por se tratar de um processo altamente agressivo às condições e propriedades dos materiais, a falta de correção e reparo dos danos ocasionados pelo processo podem gerar consequências desastrosas para uma estrutura, a depender da intensidade e comprometimento de suas capacidades estruturais. Diante disso, o presente trabalho objetiva analisar as manifestações patológicas de corrosão encontradas em estruturas metálicas, com a finalidade de identificar suas causas e abordar, por meio de estudo comparativo, técnicas de prevenção e reparo desses elementos. Efetuou-se, portanto, uma revisão.........

This research focuses on studying the social implications that motivate conformity purchase intention of apparel products through an empirical analysis. Based on previous literatures on consumer conformity and purchase intention, reviews and recommendations, degree of conformity, social norms and social values, and gender, taken as independent variables are the social implications defined and tested on the dependent variable conformity purchase intention. From the variables defined, hypotheses were developed and tested on 300 people from the United Kingdom through a survey questionnaire. Correlation and regression analysis and the general linear analysis of co-variance were performed using the SPSS 22.0 software. Regression analysis showed reviews and recommendations having a p-value of significance of 0.250.........

The research of hardness and toughness with regard to various input parameters is the focus of the project optimization of MIG welding settings for enhancing welded joint strength. Gas Metal Arc Welding is a procedure in which heat is generated by an arc between a consumable metal electrode and the work piece, with an argon gas shield supplied externally. This experimental work intends to reduce the number of level analyses of welded area of a mild steel specimen by employing a factorial design technique to optimise various Gas Metal Arc welding parameters such as wire feed rate, welding current, and inert gas supply rate. The link between various process parameters and weld deposit area was investigated using a factororial design technique.

This work addresses the importance of research and application of maintenance systems in buildings. The article started from a bibliographical research on the need to implement a strategic planning with the aim of building maintenance in order to ensure proper functioning and prolong the useful life of buildings. As the objective of the work was to address planning measures for maintenance, there was a literature review on the proposed topic. The research was descriptive with a qualitative approach. For the elaboration of the research, Google Scholar was used for data collection, which are characterized by being articles, norms, dissertations and monographs published in a maximum period of five years. The importance of the Building Inspection was observed as a primary planning measure, as it gives a detailed overview of the building and later preventive actions based on the frequency that, combined with facilities management tools, can be a great ally of the useful life of the buildings.

In the current age of the Fourth Industrial Revolution, the digital world has a wealth of data, such as Internet of Things (IoT) data, cyber security data, mobile data, business data, social media data, health data, etc. To intelligently analyze these data and develop the corresponding smart and automated applications, the knowledge of artificial intelligence (AI), particularly, machine learning (ML) is the key. Various types of machine learning algorithms such as supervised, unsupervised, semi-supervised, and reinforcement learning exist in the area. Besides, the deep learning, which is part of a broader family of machine learning methods, can intelligently analyze the data on a large scale. In this paper, we present a comprehensive view on these machine learning algorithms that can be applied to enhance the intelligence and the capabilities of an application. Thus, this study's key contribution is explaining the principles of different machine learning techniques and their applicability in various real-world application domains, such as cyber security systems, smart cities, healthcare, e -commerce, agriculture, and many more.

In food processing engineering, heat and mass transfer problems are encountered and cannot be solved by thermodynamics reasoning alone but requires food analyses based on heat kinetics principles. The objective of this work is to determine the rate of moisture removal within specified machine capacity and the effect on nutritional composition and sensory attributes of various fish and meat products. Proximate composition of fresh and finished beef, Atlantic mackerel fish, chicken and herring fish was carried out. Sensory acceptability of the product was also considered. Moisture removal rate of the machine for fish and meat products was calculated to be 25.87 %/hr (Atlantic mackerel), 23.37 %/hr (herring fish); and 28.05 %/hr (beef) and 24.51 %/hr (chicken) respectively. The volumetric capacity was found to be 0.0048 m3 (mackerel and herring fish), 0.0061 m3 (beef) and 0.0095 m3 (chicken). Proximate analysis......

In this work the corrosion inhibition properties of Bitter leaf (Vernonia amygdalina) and Banana stem (Musa Acuminata) extracts on corrosion of mild steel in acidic medium was investigated and the two inhibitive properties were compared using weight loss method, different corrosion rate of the sample, inhibition efficiency and observations through the FTIR and SEM. The FTIR was used to determine the functional groups presence in the extract and the SEM was used to determine the morphology of the mild steel before and after inhibition extract treatment. The effect of concentration at different temperature (303K -313K) was studied to determine the inhibitory potentials of the extracts. Characterization of both Bitter leaf (Vernonia amygdalina) and Banana stem (Musa Acuminata) was also carried out......
